In sociology, the term ‘technology’ does not simply refer to machines and scientific instruments. It also implies an appropriate attitude, habits of thought and action. The reason is obvious. In the absence of the latter, mere installation of machines does not yield the desirable result. In this regard the observations of G.M. Foster are very relevant.

“Technological development is, indeed, a complex process. It does not simply mean the overt acceptance of material and technical improvements. It implies a cultural, social and psychological process as well.” Some writers, therefore, prefer to use the term socio- technological development.
